Description

Modular platform helmet that is wirelessly connected to a smartphone}

The present invention relates to a helmet, and in particular, by utilizing resources such as sensors basically built into smartphones without a separate network, it is possible to ensure the safety of workers and efficient work control in industrial sites even without installing separate sensors and network equipment. It relates to a modular platform helmet having a means.

Workers working at industrial sites may be exposed to various risks depending on the type of work performed at the industrial site. At construction sites, the risk of falling or impact is a major risk factor, and in chemical factories or general manufacturing sites where chemical products are used such as pretreatment, heating, cleaning, and application, inhalation of toxic substances poses a risk. In integrated processes where rollers, presses, or cutters are installed, there is a constant risk of major accidents due to insufficient safety devices due to material loss when the process is stopped.

It is most important that safety devices are in place to prevent such accidents in advance. However, in the event of an accident, emergency measures can be taken to minimize damage, but missing the golden time can lead to serious injury or death. Prevention is also important.

Recently, to prevent such accidents, devices incorporating the latest IoT technology are being released attached to hard hats or wearable devices. For example, Registered Patent Publication No. 10-2335915 (publication date: August 27, 2021) proposes equipment with a biometric information sensor worn on the chest and a helmet with GPS and camera equipment attached.

However, in the prior art, including the registered patent publication, various sensors must be attached to the body when constructing a system for safety management, and a separate central receiver is installed to directly receive signals from various sensors attached to the body through short-distance wireless communication. Because it must be provided, costs and inconveniences may arise due to the cost of building the system and the burden on workers to wear it.

Registered Patent Publication No. 10-2335915 (Publication Date: 2021. 08. 27)

Accordingly, the present invention equips the hard hat with only the minimum means to utilize resources such as sensors or communication networks basically built into the smartphone itself without a separate sensor or network system, so that even if a separate short-range network system is not built, the operator can The current status of the worker can be transmitted in real time to fellow workers and superiors, and even if a separate sensor is not installed, the worker's fall, pulse, or real-time environmental temperature can be checked. We aim to provide a modular device platform helmet that eliminates the need for supervisors to carry excessive radios as radio communication is inevitable.

The specific structural or functional descriptions presented in the embodiments of the present invention are merely illustrative for the purpose of explaining the embodiments according to the concept of the present invention, and the embodiments according to the concept of the present invention may be implemented in various forms. In addition, it should not be construed as being limited to the embodiments described in this specification, and should be understood to include all changes, equivalents, and substitutes included in the spirit and technical scope of the present invention.

Hereinafter, the present invention will be described in detail with reference to the attached drawings.

As shown in FIGS. 1, 4, and 5, the modular device platform helmet according to the present invention includes a normal safety helmet 10, a platform 20 installed on the safety helmet 10, and the platform 20. It includes a mounted device module 30 and a wireless communication module 40.

There is no limit to the type of safety helmet 10, and any safety helmet worn not only for work safety but also for leisure or driving or other activities may fall under this category.

The platform 20 is installed inside or outside the safety helmet 10 as shown in FIGS. 4 and 5, and has a groove or guide on which the device module 30, which will be described later, can be mounted in a detachable or sliding manner. It is a small structure that When the platform 20 is installed inside the hard hat 10, as shown in FIG. 4, the platform tunnel 11 in the hard hat 10 is recessed on the inside and on the outside to prevent pressure from being applied to the top of the wearer's head. When viewed from above, it may be formed in a long, protruding form. The platform tunnel 11 has a space inside which the platform 20 can be contained.

The device module 30 is a device that generates an electronic signal or voice signal to be transmitted to the smartphone 60, or visually or audibly outputs an electronic signal or voice signal transmitted from the smartphone 60.

That is, the device module 30 is a device that remotely assists the sensor, short-range communication module 63, or call module built into the smartphone 60 from a short distance, or remotely supports the app 62 installed on the smartphone 60. It is a device that operates. Therefore, the device module 30 is a mechanism that assists in utilizing the resources built into the smartphone 60.

The wireless communication module 40 serves to connect the device module 30 installed on the safety helmet 10 and the short-range communication module 63 of the smartphone 60. The installation location of the wireless communication module 40 is not necessarily limited to the position in Figures 1 or 4. Although the Bluetooth communication module is widely used as the wireless communication module 40, the wireless communication module 40 is installed in the platform helmet according to the present invention. )'s specific implementation form is not necessarily limited to the Bluetooth communication module.

Conventionally, a worker's fall, impact accident, or collapse due to an accident is monitored wirelessly by a central network server in real time through the hard hat worn by the worker or a tilt sensor or gravity sensor worn on the body, so the safety helmet or Various sensors must be installed directly on the body.

and environmental sensors, such as certain gas detection sensors, including carbon dioxide sensors, or temperature sensors or pressure sensors, that are worn on the worker's body or installed in a hard hat so that problems with atmospheric composition, pressure, or temperature in the worker's environment can be detected. Because they are directly connected wirelessly to the central network and must be monitored directly from the central control room or situation room, network construction costs are excessive, and in cases where the central control room is unable to check the situation, even if an accident occurs, prompt response is required. There is a problem that cannot be addressed.

In addition, even if an environmental problem or an accident such as a fall or shock occurs in a situation where a specific worker is faced, other workers around him may not be aware of this, and if other workers around him are to be able to recognize this as well, the central Since a receiving means that can receive a warning signal that the server detects and transmits back to the surroundings must be installed on the body or hard hat of every worker, this can also be a huge loss in terms of cost.

Also, in the case of large sites, the person in charge or manager sets the radio to communicate on a separate frequency for each worksite due to the limitations of the radio wave transmission and reception range, and each time the site is moved, the person in charge or manager sets the frequency to match the frequency of the site to be moved. Because it was cumbersome to adjust, it was necessary to carry as many radios as the number of radios at each site and set the frequency of each radio in advance for the corresponding site, causing considerable inconvenience.

Wi-Fi is sometimes applied to unify communication between sites, but in this case, workers in the field must wear a separate transceiver that can wirelessly connect to Wi-Fi, such as a hard hat or body, and a system to monitor the location of field workers. There is a problem that significant costs are incurred to build the entire system due to the development of the program.

At this time, there is a method of using the smartphone 60 instead of the radio through the app 62 that is installed on the smartphone 60 and allows the smartphone 60 to be used like a radio. However, each time you radio, you must take off your gloves and use the smartphone 60 as a walkie-talkie. There is a complicated problem of having to turn on the screen of (60) and run the app to operate it.

As such, in the past, all aspects of communication for safety and work efficiency in industrial sites were difficult to achieve without a central network system, and establishing a central network communication system required significant costs, and centralized control There is also the problem of increased burden.

To solve this problem, in the modular device platform helmet according to the present invention, as shown in FIG. 1, considering that all workers carry a smartphone 60,

1. By utilizing the sensor 61 built into the smartphone 60, such as a tilt sensor, gravity sensor, proximity sensor, or temperature sensor, there is no need to install the sensor directly on the hard hat 10 or the worker's body,

2. If a sensor that is not installed in the smartphone 60, such as an atmospheric component detection sensor such as a carbon dioxide sensor or a pressure sensor, is needed, the sensor is installed on the hard hat 10 or the worker's body, but the sensor installed at this time is centrally located. It is connected to the short-range communication module 63 of the smartphone 60 carried by the worker through short-range wireless communication without the need to be directly connected to a specific network, and when sensor detection information is received by the smartphone 60, the smartphone 60 Monitoring information from industrial sites can be displayed in real time on the manager's personal PC (70) through the web server (90).

3. Regarding the problem of communication between workers, when a PTT that can remotely operate the radio app of the smartphone 60 is installed on the hard hat, if you want to communicate, turn on the screen of the smartphone 60 and take off your gloves. Communication may be possible by simply pressing the PTT button installed on the hard hat 10 without the cumbersome procedure of operating the smartphone 60.

Therefore, the modular device platform helmet according to the present invention uses the web server 90 even if the sensor 61 built into the smartphone 60 is used or the sensor 61 not built into the smartphone 60 is directly installed. Since the conventional on-site central network can be replaced by the smartphone 60, cost and efficiency are significantly improved, and the device module 30, which is a mechanism that can remotely control the app 62 of the smartphone 60, is provided. By being installed on the hard hat 10, there is no need to install a separate terminal on the hard hat or the worker's body that performs two-way communication with the central field network and performs calculations at the same time.

Therefore, in the platform helmet according to the present invention, the device module 30 is first a mechanism that remotely transmits a touch action or voice input input to the smartphone 60 to the smartphone 60, or It is a device that assists the function of one of the installed sensors 61, a device that receives a digital voice signal from the smartphone 60, converts it to analog, and then amplifies it, or is a device built into the smartphone 60, such as a carbon sensor. Although not yet implemented, it may consist of any one or a combination of two or more sensors for industrial safety.

Therefore, looking at the industrial field as a whole, as shown in FIG. 2, the system using the modular device platform helmet according to the present invention includes the device module 30 and the smartphone 60 installed on the hard hat 10 when there are multiple workers. ) exist in plural numbers as many as the number of workers, and the smartphone 60 carried by each worker is connected to the web server 90 through the base station 80, and the manager's PC 70 is also connected to the web server ( 90), so two-way transmission of information is possible from the manager to all workers at each site through the web server 90.

At this time, for example, if a worker has a fall accident, is hit on the head, or is suffocated due to excessive carbon, the tilt sensor built into the smartphone 60 or the device module 30 installed on the safety helmet 10 ) The impact sensor or carbon sensor that constitutes the sensor transmits the sensor's measurement information to the smartphone 60, and this information is sent as an alert to the manager's PC (70) or other worker's smartphone (60) through the web server (90). A signal can be generated.

Even if a separate on-site management network is not established, an excellent safety management system can be established in any industrial site, no matter how large, as long as the device module 30 and the smartphone 60 installed on the platform 20 of the hard hat 10 are installed.

In this case, the wireless connection between the smartphone 60 and the device module 30 installed on the hard hat 10 is short-range communication including a typical Bluetooth method, and this is also a simple communication module installed on the hard hat 10 without a separate network. Communication can be accomplished with just that.

And at this time, the sensors 61 installed on the smartphone 60 include motion-related sensors including a gravity sensor, an accelerometer, and a rotation vector sensor, location-related sensors including a magnetic field sensor and a proximity sensor, a humidity sensor, and an illumination sensor. and environmental measurement sensors including an ambient pressure sensor and a temperature sensor, a heart rate sensor, and a lidar scanner.

And the voice input performed by the device module can be used when an app that uses the Internet call function is used. At this time, the voice input may specifically be a microphone wirelessly connected to the smartphone 60.

Additionally, the device module 30 may include wireless bone conduction earphones 326, which are not directly installed on the platform 20 but are installed at the ears of the wearer of the safety helmet 10. Due to the bone conduction earphones 326 and microphone 327, workers can hear surrounding sounds and communicate with other workers and managers via the smartphone 60, even at noisy work sites.

And since the app 62 installed on the smartphone 60 operates in conjunction with the smartphone 60's own operating system and the web server 90, there is no need for a separate computing means or database used to build a separate network. do.

Therefore, as shown in FIG. 3, the short-range communication module 63 and various sensors 61 built into the smartphone 60, the app 62 installed on the smartphone 60, and the operating system of the smartphone 60 The platform helmet according to the present invention is configured in such a way that the resources of the smartphone 60 can be utilized to the maximum so that it can function as a network system for promoting safety in industrial sites.

However, the device module 30 installed on the safety helmet 10 may be a sensor or a device that assists the function of the smartphone 60, so its form may vary. In order for various types of devices to be installed on the safety helmet 10, the safety helmet 10 had to be manufactured to fit the shape of each device or sensor in the device being installed. If the safety helmet 10 has to be designed anew every time additional sensors or devices of different types are installed, it may not be possible to install it on the existing safety helmet 10, or it may be installed separately so that the additional sensors or devices can be worn. A wearable device may be needed.

In order to ultimately solve this problem in the modular device platform helmet according to the present invention, as shown in FIG. 4, the safety helmet 10 is provided with a mount rail 21 on which one or more mounting mechanisms 32 can be sequentially mounted. The modularized platform 20 may be provided inside or outside the safety helmet 10.

At this time, the platform 20 is provided with a module container 31 that can be moved while being guided along the mount rail 21 corresponding to the number of device modules 30.

Even if the shape of the device module 30 is diverse, the module container 31 is elastically contracted as shown in FIG. 7 to prevent the device module 30 from falling off while being stably mounted inside the module container 31 and then absorbs an external force. An elastic holder 314 that can be restored to its original state when removed may be installed at the entrance or inside the module container 31. There is no limit to the specific material of the elastic holder 314 as long as it has elasticity. It fills the entrance or internal space of the module container 31 and is pushed and contracts only at the moment when the device module 30 is mounted, thereby forming the device module 30. When mounted, it expands again to prevent the device module 30 from being separated.

In this way, regardless of the type of sensor or device, it is mounted on the module container 31, and when the module container 31 is sequentially mounted on the mount rail 21 installed on the platform 20, the resources built into the smartphone 60 If the device module 30 needs to be replaced or added because new resources are needed or changes are required, the module container 31 can be simply replaced by moving or adding it from the mount rail 21. I can make changes.

What is particularly important at this time is that in order to enable installation in a standardized module form regardless of the type of sensor or device, power must be supplied equally even if each sensor or mechanism forming the device module 30 is different.

To this end, the modular device platform helmet according to the present invention must be installed with a battery module 50 connected to the guide tunnel (not shown) or mount rail 21 forming the platform 20, as shown in FIG. 5, Electrodes or cables through which power is transferred from the battery module 50 are installed along the longitudinal direction of the mount rail 21, or a guide tunnel or part of the mount rail 21 itself is formed as a conductor. An external electrode 312 that is in close contact with or connected to an electrode or cable may be formed on a predetermined portion of the outer surface of the module container 31.

And, an internal wiring connected to the external electrode 312 and an internal electrode 321 formed at the end of the internal wiring are installed inside the module container 31, and the internal electrode 321 is installed in the module container 31. It may be connected to the device module 30 and supply power to the device module 30.

Therefore, each sensor or device that makes up the device module 30 may have different electrode positions or connection methods as their shapes are different, but these individual sensors or devices are located inside the module container 31 as shown in FIG. 6. Power can be supplied by combining a terminal with an internal electrode 321 corresponding to a terminal for connecting a provided device, and each module container 31 has an external electrode 312 provided on the outer surface of the module container 31 and Since the rail electrode 211 formed on the mount rail 21 is always maintained in contact, power can be supplied.

As a result, the modular device platform helmet according to the present invention is connected to the smartphone 60 through short-distance communication and receives power from the battery module 50 so as to maximize the use of the resources built into the smartphone 60. Since the device modules composed of can be freely mounted, detached, or added in a standardized form, a system capable of monitoring more types of information at a lower cost is built even though there is no need to build a separate on-site network system as in the past. It can be done as much as possible.

The present invention described above is not limited to the above-described embodiments and the accompanying drawings, and various substitutions, modifications, and changes are possible without departing from the technical spirit of the present invention in the technical field to which the present invention pertains. It will be clear to anyone with ordinary knowledge.
